Here's the PHP script that uses information from WorldMapOverlay.dbc and WorldMapArea.dbc, to generate a single map from tiles and overlays.
Code:
<?
header("Content-Type: image/png");
$name=$_GET['n'];
$mysqli = new mysqli("localhost", "root", "password", "WoWMapStuff");
if ($mysqli->connect_errno) {
echo "Failed to connect to MySQL: (" . $mysqli->connect_errno . ") " . $mysqli->connect_error;
}
$query1="SELECT ID,MapID FROM worldmaparea WHERE AreaName='$name'";
$res=$mysqli->query($query1);
$row=$res->fetch_assoc();
$id=$row['ID'];
$mapID=$row['MapID'];
$mapData = Array();
$query2 = "SELECT DISTINCT Name,Width,Height,X,Y FROM worldmapoverlay WHERE WorldMapAreaID='$id' AND Name <> '' AND Width > 0 AND Height >0";
$res=$mysqli->query($query2);
while ($row = $res->fetch_assoc()) {
$mapData[]=Array($row['Name'],$row['Width'],$row['Height'],$row['X'],$row['Y']);
}
if(file_exists("WorldMap/$name/".$name."1.png"))
{
$phase="";
}else{
$phase="1_";
}
$im = imagecreatetruecolor(1002,668);
$im1 = imagecreatefrompng("WorldMap/$name/".$name.$phase."1.png");

$im3 = imagecreatefrompng("WorldMap/$name/".$name.$phase."3.png");
$im4 = imagecreatefrompng("WorldMap/$name/".$name.$phase."4.png");
$im5 = imagecreatefrompng("WorldMap/$name/".$name.$phase."5.png");
$im6 = imagecreatefrompng("WorldMap/$name/".$name.$phase."6.png");
$im7 = imagecreatefrompng("WorldMap/$name/".$name.$phase."7.png");
$im8 = imagecreatefrompng("WorldMap/$name/".$name.$phase."8.png");
$im9 = imagecreatefrompng("WorldMap/$name/".$name.$phase."9.png");
$im10 = imagecreatefrompng("WorldMap/$name/".$name.$phase."10.png");
$im11 = imagecreatefrompng("WorldMap/$name/".$name.$phase."11.png");

$index=1;
$ix=0;
$iy=0;
function mapChunk($width,$height,$name,$zone)
{
$im=imagecreatetruecolor($width,$height);

$tw=ceil($width/256);

$imx=imagecreatefrompng("Worldmap/$zone/".$name.$index.".png");
imagecopy($im,$imx,($x*256),($y*256),0,0,$cwidth,$cheight);
$index++;
}
}
return $im;
}
for($i=0;$i< count($mapData);$i++)
{
imagecopy($im,mapChunk($mapData[$i][1],$mapData[$i][2],$mapData[$i][0],$name),$mapData[$i][3],$mapData[$i][4],0,0,$mapData[$i][1],$mapData[$i][2]);
}
imagepng($im);
imagedestroy($im);
?>
Finally, this is the script used to parse the dbc files and insert it into the database
Code:
<?

}
function prepStrings($stringTable)

{

}
}
for($x=0;$x < count($offsets)-1;$x++)
{
$strings[$offsets[$x]]=substr($stringTable,$offsets[$x],$offsets[$x+1]-$offsets[$x]-1);
}
return $strings;
}
function makeTable($data,$fields,$rowSize)
{
$dataTable=Array();
$rows=str_split($data,$rowSize);
for($x=0;$x<count($rows);$x++)
{
$dataTable[]=str_split($rows[$x],4);
}
return $dataTable;
}
function formatTable($dataTable,$stringCols,$floatCols,$strings)
{
for($x=0;$x < count($dataTable[0]);$x++)
{
for($y=0;$y < count($dataTable);$y++)
{
if(in_array($x,$stringCols)){

}elseif(in_array($x,$floatCols))
{

}
else
{
$dataTable[$y][$x] = sUnpack("l",$dataTable[$y][$x]);
}
}
}
return $dataTable;
}
/* DBC files don't contain any type information or field names,
